The IMBR Initiative was founded at Georgetown University Law Center in 2008. Since then, the text of the IMBR and the other IMBR Tools has been drafted in consultation with migrants and other civil society actors; policymakers at the national, regional and international levels; and students and scholars of migration. The early work of the IMBR Initiative was managed as a collaboration between the American University in Cairo, the Global Law Scholars program at Georgetown University Law Center, the Migration Studies Unit at the London School of Economics and the Minerva Institute at Hebrew University. In addition to past support by those institutions, the IMBR Initiative has received support from the International Migration Initiative of the Open Society Foundations.
A detailed history of the early work of the IMBR was published in 2010 in Volume 24 of the Georgetown Immigration Law Journal and is available here.
